METHOD FOR PRODUCING CERAMIC COMPOSITE FOAMS WITH HIGH MECHANICAL STRENGTH

摘要

The present invention relates to a ceramic foam structure characterized in that it is produced by using a reaction bonded power. The invention also relates to a method for producing a ceramic foam structure, characterized in that the method comprises the following steps: providing a reaction bonded power blend, producing a stable slurry of the powder blend in water or in a solvent, producing a foam, drying said foam, calcinating said foam, oxidizing said foam, and a final thermal treatment Using this method, ceramic foams having better mechanical properties compared to classical foams can be prepared.
